Not only has she helped me lose weight and tone my body but has also been a huge influence in self-confidence and self esteem. I would recommend Nikol to anyone. Her knowledge of the body, muscles and dance background make her one of the most talented and respected trainers I have ever met. I encourage anyone to look into her services; she has been a blessing to me!”

As a fitness expert and former professional ballet dancer, I know all of the best training techniques to get you a lean, bulk-free body. You won’t find these exercises anywhere else or at your local gym because they have been created by me, a ballerina turned fitness trainer!  These exercises have been designed by me specifically for you, the woman who wants a slim and toned yet not overly-muscular body.

These clients continue to trust me to get them the results that they want and now the same opportunity is available you.

“I gained a lot of weight during my pregnancy. Balancing taking care of my baby and working out was quite a challenge. Four months after I had my son, I finally got frustrated with the lack of results and that’s when I found Nikol. Since I've been working with Nikol at her Del Mar personal training studio, doing 30 minute personal training sessions 3 times per week, I've lost 16 inches so far and at least 15 pounds within the last 2 and a half months! I could see and feel results within the first week.  I would recommend Nikol to everyone and her 30 minute sessions are very convenient for me as a busy mom as the results are absolutely amazing!”

-Christina Sikes, San Diego, California

“I’m now below my pre-pregnancy weight!”

"Nikol has completely transformed my body. I knew she was the perfect trainer for me from the second we met. Nikol took the time to listen to me about how I felt and what my goals were. She pushed me in my workouts and continually built me up with her unconditional support. She genuinely cares about her clients and wants them to look and feel good. She continues to push me and has inspired me to take pride in my body and my health. I have gained an incredible sense of self confidence and can honestly say that I LOVE my body. Training with Nikol is the best decision I have ever made!"

I used to dread going to the gym or even a simple jog but now I look forward to the days we train together! Nikol excels at working on exactly what your particular body needs are and helping to strengthen weak areas. I absolutely love Nikol as a trainer, and LOVE the results!”

“Looked toned on my wedding day!”

"Nikol is amazing to work with. I initially started working with her to get in shape before my wedding. She graciously moved her schedule around so that I could seriously get to work before my big day. Even though it has only been 5 weeks or so, I've created healthier eating habits, lost several inches around my stomach and other areas, and was noticeably more toned in my arms and back in my wedding dress. I can't wait to continue working with her, even after my wedding has happened. Nikol is professional, reliable and kind, and you will enjoy working with her. "

-Sara N., Carlsbad, California
